“New research found that natural immunity offers exponentially more protection than COVID-19 vaccines.”

“Harvard Medical School professor Martin Kulldorff said research showing that natural immunity offers exponentially more protection than vaccines means vaccine passports are both unscientific and discriminatory, since they disproportionately affect working class individuals.

“Prior COVID disease (many working class) provides better immunity than vaccines (many professionals), so vaccine mandates are not only scientific nonsense, they are also discriminatory and unethical,” Kulldorff, a biostatistician and epidemiologist, observed on Twitter.”
